Yes you can.
However you need to be prepare the initial powder film for optimum adhesion required by the paint.
One of the common processes to prepare is to buff or sand paper the surface (the initial powder coated fim) and then use the paint. In term sof chemistry PVDF, PU etc are good options for paints over powder coatings.

Creating a good profile for the paint to adhere to is essential. 80 grit sandpaper or scotchbrite will create a good surface for paint to adhere to.

SteveNO. Powder coating is undertaken by stripping the metal back to a clean, grease free surface. The powder is than sprayed on to the metal and its then fired in a kiln. This melts the power to the metal surface. If there where paints on the surface and these are not powder coated on i.e. enamel paint then the powder coat will not adhere well and the finish cannot be guaranteed
Paints also tend to bubble up when being cooked in an oven at 400 degrees. This ruins the powder coat finish.
